Microplastic impacts archaeal abundance, microbial communities, and their network connectivity in a Sub-Saharan soil environment

This study examined how plastic waste that has broken down into tiny microplastics affects soil microorganisms in Kenya. Researchers found that microplastics reduce the number and diversity of helpful archaea (ancient microorganisms important for nitrogen cycling) and disrupt how different microbes interact with each other in soil. While microplastics carried slightly more potentially harmful bacteria, they were much better at spreading dangerous fungi, suggesting plastic waste poses a significant threat to soil health in Sub-Saharan Africa.

Arbuscular mycorrhiza suppresses microbial abundance, and particularly that of ammonia oxidizing bacteria, in agricultural soils

This study examined how beneficial fungal partners of plants (arbuscular mycorrhizal fungi) affect soil bacteria that convert ammonia to nitrate. Using 50 different soils from Czech agricultural fields, researchers found that these fungi suppress ammonia-oxidizing bacteria, but surprisingly this happens even when ammonia levels in soil are high. The findings suggest the relationship between these microorganisms is more complex than simple competition for nutrients.

Arbuscular mycorrhiza suppresses microbial abundance, and particularly that of ammonia oxidizing bacteria, in agricultural soils

This study examined how a beneficial fungus called arbuscular mycorrhiza affects bacteria that break down ammonia in soil. Researchers tested 50 different agricultural soils and found that the fungus suppressed ammonia-oxidizing bacteria populations. Interestingly, the presence of the fungus actually increased ammonia levels in soil while decreasing nitrate, suggesting the relationship is more complex than simple competition for nutrients.

Hydrothermal liquefaction aqueous phase mycoremediation to increase inorganic nitrogen availability

When biomass is converted to biofuel through a heating process called hydrothermal liquefaction, it produces a waste liquid containing nutrients but also toxins. Scientists used a type of fungus called Trametes versicolor to clean up this waste and convert the nitrogen into forms that plants can use. After three days of treatment with the fungus, nitrogen levels that plants can use increased dramatically. Adding helpful bacteria further improved the results, making this waste potentially usable as a fertilizer for growing vegetables hydroponically.

Hydrothermal liquefaction aqueous phase mycoremediation to increase inorganic nitrogen availability

This research shows that a common mushroom fungus called Trametes versicolor can clean up wastewater produced during the conversion of food waste into biofuel. The fungus transforms hard-to-use nitrogen compounds in the waste into forms that plants can absorb. After three days of treatment, the nitrogen that plants can use increased dramatically. When bacteria known for converting ammonia to nitrate were added to the fungal treatment, the results improved even more, suggesting this waste could eventually be recycled as a fertilizer for growing plants in water-based farming systems.
